Evaluasi Karakteristik XBee Pro dan nRF24L01+ sebagai Transceiver Nirkabel

Chosing transciever module as a media for a digital transmission data has becoming a serious problem for a designer to design a wireless communication system. In this research, author do the evaluation for a two transceiver module that are XBee Pro and nRF24L01+, the purpose is to chose which the right transceiver module that designer need to make a Wireless Sensor Network (WSN) system. The evaluation was done by sending a data in ASCII character/ bytes as continuous and sequensial method using serial communication UART. When data rate is set to 250 Kbps mode, XBee Pro data rate is 27 Kbps and nRF24L01+ 16Kbps for serial communicaton UART purpose. nRF24L01+ is better at sending a streaming data (continuous) than XBee Pro, and also nRF24L01+ has a fastest Round Time Trip (RTT) that are 0,003 sec while XBee Pro only 0,036 sec. For indoor application XBee Pro has a better perform because it work better until 4 brick wall while nRF24L01+ only 2 brick wall.
